BACKGROUND

Printers and multi-function devices perform various functions for users. These functions may include printing, faxing, and/or scanning text and images. The price of these devices is often based on level of performance and features of a particular device. For example, a device that includes facsimile and scanning functions in addition to printing functions may be priced higher than a device that includes only printing functions. Similarly, a device that performs printing functions at a higher speed or resolution may be priced higher than a device that performs printing functions at a lower speed or resolution.

A user may purchase a printer or multi-function device with a certain set of features based on the user's present and future needs. Because the set of features of a printer or multi-function device is generally not alterable, the user may have the choice of purchasing a printer or multi-function device that either meets some but not all of the user's needs at a lower price or meets all of the user's needs but has features that a user does not need at a higher price. In addition, the user's needs may change over time such that the user may desire an increased or a decreased set of features of the printer or multi-function device. In many cases, the user may need to purchase a different printer or multi-function device to accommodate the user's changed needs. It would be desirable for a user to be able to purchase a printer or multi-function device that closely met the user's needs both at the time or purchase and over time.

SUMMARY

In an exemplary embodiment, the present disclosure provides a system comprising a processor and a memory comprising firmware. The firmware is executable by the processor to cause the processor to operate a print mechanism in accordance with a first state associated with a capability of the print mechanism, change the first state associated with the capability to a second state in response to receiving first information from an external interface, and operate the print mechanism in accordance with the second state associated with the capability.

The user may extend or increase these licensed limits by paying for additional time or uses. In response to additional use being enabled, printer engine 200 allows the user to use the functions for the time or number of uses paid for by the user. In some embodiments, only some functions may be offered on a per-use license basis. For example, the user may purchase high resolution scans or high resolution enhanced photo printouts to enable these functions.

Referring back to FIG. 5, the list of capabilities that may be enabled by the user from block 502 may include performance capabilities, upgrade capabilities, functional capabilities, and renewal capabilities as described above. The user may select one or more of the capabilities to be enabled by providing an input to computer system 104. Computer system 104 receives the capability selection from the user as indicated in a block 504. Computer system 104 provides information associated with the capability selection to server 102. The information may include payment information or billing information to cause the user to pay for enabling the selected capabilities. In response to receiving and verifying the information from computer system 104, server 102 provides information associated with the selected capabilities to computer system 104. In response to receiving this information, computer system 104 provides the information to printer 108. Printer 108 enables the selected capabilities using the information as indicated in a block 508. The information from server 102 may include one or more encryption keys configured to enable capabilities of printer 108. The information may also include a firmware update to replace firmware 206 or additional firmware for use in conjunction with the existing firmware 206.

In response to a capability being enabled, print engine 200 allows the user to use the selected capability. In particular, print engine 200 operates print mechanism 208 and functional unit 210 in accordance with one or more indicators associated with one or more capabilities of print mechanism 208 and functional unit 210. In one embodiment, the indicators each comprise an encryption key stored on printer 108. In other embodiments, the indicators may comprise other types of information stored on computer system 104, on server 102, or in other locations.

Print engine 200 determines a state associated with a capability by examining an indicator associated with the capability. Depending on the type of capability, the state may indicate whether the capability is enabled or disabled, or the state may indicate a level of performance associated with the capability. For example, in an embodiment where functional unit 210 comprises a facsimile device, print engine 200 may access an indicator associated with the facsimile device to determine whether the facsimile device is enabled or disabled. The state of the indicator associated with the facsimile device may be changed, e.g., from disabled to enabled, in response to the user enabling the facsimile device as described above. The state of the indicator associated with the facsimile device may also be changed, e.g., from enabled to disabled, in response to a license associated with the facsimile device being used-up or expiring.

As another example, print engine 200 may access an indicator associated with print mechanism 208 to determine the speed or resolution to apply to a print job. The state of the indicator associated with print mechanism 208 may be changed, e.g., from a lower level of performance (e.g., 10 pages per minute) to a higher level of performance (e.g., 20 pages per minute), in response to the user selecting and paying for the higher level of performance as described above. The state of the indicator associated with print mechanism 208 may be changed, e.g., from a higher level of performance to a lower level of performance, in response to a license associated with print mechanism 208 being used-up or expiring.
